Product Alert

Separate accessory recommended for Lulzbot users!

NInjaFlex adheres exceedingly well to PEI print surface. We strongly recommend applying PVA glue (white school glue) directly on the print surface using a glue stick (such as Elmer's® brand) before printing to ensure easy part removal.

The Market Leading Flexible Filament

NinjaFlex® flexible filament leads the industry thanks to its superior flexibility and longevity compared to non-polyurethane materials. Its consistency in diameter and ovality (roundness) outpaces other polyurethane materials. Made from a specially formulated thermoplastic polyurethane (TPU) material, this patented technology boasts a low-tack, easy-to-feed texture. The result is uniquely flexible, strong prints ideal for direct-drive extruders.
